A high pressure oil/polymer filtering system was designed and tested to find its optimum design criteria. Various shapes and different mesh sizes of candle-type metal-fiber filter elements were used to determine the effects of the shapes, mesh sizes, and positions of the filter elements on the pressure drop across the filter elements. A pressure vessel was designed to fit the candle-type metal-fiber filtering media elements using a stainless steel division plate. The pressure drop across the division plate of the pressure vessel, i.e., across the filter, was measured and plotted against the dimensional parameter µQ/A w . The pressure drop was directly proportional to µQ/A w . The effects of various shaped (different length) filter elements, mesh size and filter layout on the pressure drop were studied.
